Be it known that I, EDWARD PoHL, a subject of the Emperor ofAustria-Hungary, and a resident of Paterson, county of Passaic, State ofNew Jersey, have invented certain new and useful Improvements inApparatus for Lustering and Finishing Silk Filaments, of which thefollowing is a specification, reference being had to the accompanyingdrawings, forming a part thereof.

In apparatus of the class to which this invention relates means areprovided for immersing silk filaments in a bath containing a suitableliquid and for drying and lustering the filaments by carrying them fromthe bath over a heated surface. Certain means is provided for removingthe surplus moisture from the filaments as they come from the bath andfor initially drying same; but the final drying takes place during thetime the filaments pass over the heated. surface. In operating machinesof this character I have found that a considerable quantity of solutionfrom the filaments becomes deposited upon the approach end of the heatedsurface, where it cakes and dries, thereby seriously interfering withthe efficiency of the apparatus and tending to injure the filaments bydirtying them. To stop the apparatus for the purpose of frequentlycleansing this surface entails a waste of time and consequent loss; andit is the main object of this invention to provide such means as willprevent the lodgment of this material on the heated surface.

To these ends my invention consists in the provision of a heated bodyhaving a plurality of contact-surfaces over any one of which thefilaments may pass, said heated body located between the bath and theaforesaid main heated surface and held stationary during the normaloperation of the machine. The filaments are arranged to pass from thebath over any one of the contact-surfaces of the said heated body beforepassing to the main heated surface, and the said body is provided withmeans whereby it may be caused to present its several surfacessuccessively, as may be desired, whereby as one surface becomes dirtyanother clean surface may be brought into use.

I will now describe an apparatus embodying my invention and will thenpoint out the novel features in claims.

In the drawings, Figure 1 is a view in central vertical longitudinalsection of an apparatus embodying my invention. Fig. 2 is an enlargedview, partly in plan and partly in horizontal section, showing themovable heated body and contiguous parts. Fig. 3 is a detail sectionalview, on an enlarged scale, of the same.

In the device herein illustrated a bath 1 contains the required liquid,through which silk filaments 2 are drawn. The filaments then pass over asponge 3, arranged in a perforated trough 4, and over a felt pad 5,suitably supported, whereby superfluous liquid carried up by thefilaments may be returned to the bath or suitably absorbed. Thefilaments pass from the felt pad 5 over a heated absorber 6, comprisinga perforated steampipe 7, suitably covered with felt 8 or otherabsorbent material, and will finally pass to the heated flat surface,(designated as a whole by the reference character 9,) such heatedsurface being conveniently the top of a steamtable 10. The steam-tableis heated by means of steam-pipes comprising headers 11 andconnectingpipes 12. Pipe connections 18 are shown as leading from thefront header to the pipe 7 for the purpose of conveying steam to thelatter, steam being admitted from a suitable source of supply 13 to thefront header 11 and exhausted through a pipe 1 1 from the rear header.The approach portion of the steam-table is preferably arranged as aseparate and removable portion 15, the same being suitably secured inposition and readily removable when desired for cleaning purposes.

I make no claim herein to the above features comprising the absorber 6or the removable member 15 of the steam-table 10, as the same form partof the subject-matter of a separate copending application filed October1 1, 1905, and serially numbered 282,703.

Intermediate the bath 1 and the approach end of the steam-table 10 Ihave provided a member 16, revolubly mounted upon trunnions 17,comprising branches from the steampipes 18. This member 16 is polygonalin cross-section, being provided with a plurality of flat sides arrangedat equal distances from its axis of rotation. By reason of this and ofthe fact that the member is revoluble successive sides may be presentedfor engagement with the filaments, as is desired. Thus as onecontact-surface becomes dirty a fresh contact-surface may be broughtinto use, it being understood that the said member 16 is held stationaryduring the normal operation of the machine.

The member 16 is hollow,

and steam is admitted thereto from pipes 18 for the purpose of heatingsame. The filaments in passing from the bath will pass over one of thesurfaces of the member 16 before passing to the steam-table, and thesaid surface of the member 16 Will thus receive and remove as much aspossible of the surplus material carried by the filaments before thefilaments pass to the steam-table. As one surface of the member 16becomes caked or fouled another surface may be brought into play bypartially rotating the member, and this Without stopping the machine.Thus the surface of the steam-table 10 will largely be prevented frombeing fouled, so as to permit the practically continuous use of themachine.

The relative location of the members 6 and 16 may be varied so long asthe latter member is retained in its position intermediate the bath andthe steam-table.

The amount of work performed in an apparatus constructed in accordancewith my in vention is not only increased by reason of the time saved dueto the practically continuous operation of the machine, but the qualityof the work is improved, because the lustering which is effected by theheated surface takes place upon a surface which is always clean. Informer machines this surface was often permitted to become quite foul inorder to avoid the loss of time necessary in stopping the machine toclean same. In the present machine the surfaces of the heated body 16not in use may be readily cleaned, so that such surfaces Will again beready for successive employment Without it being necessary to stop themachine even after all the surfaces provided have been successivelyemployed.

\Vhat I claim is- 1. In a machine for finishing and lustering textilefilaments, the combination With a bath for containing liquid in whichthe filaments are to be immersed, of a heated body polygonal incross-section, the surfaces of which constitute contact-surfacesarranged to be successively employed, said heated body being stationaryduring the normal operation of the device.

2. In a machine for finishing and lustering textile filaments, thecombination with a bath for containing liquid in which the filaments areto be immersed, and a heated contactsurface over which the filaments arearranged to travel, of a heated body having a plurality ofcontact-surfaces arranged to be successively employed, said heated bodyarranged between the bath and the aforesaid contact-surface.
